l UNITE STATES -ATENr ritteno WILLIAM THURBER, OF OLEN, NEW YORK.

Specification forming part of Letters Patent N0. 40,779, dated December l, 1863.

To @ZZ whom it may concern/.-

i Be it known that l, WILLIAM THURBER, of Olean, in the county of Gattaraugus and State of New York, have invented certain new and useful improvements in machinery for titting pipe and other boxes and cutting recesses in the hubs of wagons and other vehicles 5 and the following is afull, clear, and exact description of the same, reference being had to the accompanying drawings,V making a part of this speci-cation, in which.-

Figure l represents a plany or top view of the machine. Fig. 2 shows a side view or vertical elevation. Fig. 3 shows a left-hand end View of the machine. Fig. 4 is a right-hand or front-end elevation.

My invention consists in the construction and arrangement of a skeleton face-plate or revolving chuck, the same being supported and held to rotate iirmly :in its position by series of self-adj ustingfriction-rollers, their edges being V-shaped, or they may be square, run ning in grooves in the periphery of the revolving chuck made to fit. Onto the face of this chuck carriage-wh eels of various sizes maybe clamped and secured by independent hooks or jaws at three or more points on the fellies, the center of the revolving' ch uek being open in the rear or through the drivingpulley to admit ot' an arrangement for centering, boring, or cutting a recess in the end ofthe wagon-hub without changing sides or taking ott' the wheel from j the face-plate.

My invention further consists in the movable or adjustable frame, to which the revolving skeleton face-plate and appendages are attached, together with a scale and indicator, to give the taper corresponding with the boxes being fitted, also the hinged girt or beam to support a sliding bar or shaft, on the end `of which is titted'a reversible cone which may be brought to bear either in the center hole or on the outer edge ofthe end of the hub by the actionbf a crank-lever, rack and pinion, or by a weight and cord passing over a pulley, so that the hub or wheel can be centered in Astantly and secured. in such a manner that 4", to the king-bolt u.

it more fully, refei ring to the drawings, and to the letters of reference marked thereon.

Like letters indicate the part in all of the figures.

In labor-saving machinery, and especially for working in wood, it is desirable to combine as much as possible these elements-namely, sim plici ty of construction, durability, strength, and poit ibilityan l for the purpose of accomplishing this I make for the base of my machine a frame of square timber, the side pieces, Z Z, being of sufficient length and the crosspieces Y Y being framed in at the proper places, and of such length as to make the required Width. This arrangement makes a light andstron g foundation to support the working mechanism. Upon this base I place an upright frame ot' timber supported on each side by short sills or steps X X.v These are secured together by a cross-timber, W, so as t0 be the same width as the side timbers, Z Z. In the center of the short sills X are framed vertical posts V V with a plate, U, across the top, in the center ot' which isa standard, T. yTo the cross-timber W there is framed at right angle an arm, S, which has `a rule or scale of inches, s, starting in a line with the king-bolt u, which secures the upright frame to the base.- There is anotherv arm, It, attached by a link, This arm will conform to the taper of the pipe-box placed therein, and by adjusting the frame to the angle found by this process a most perfect tit of the box can be made in the hub. To the end of the arm S is a`link, t, connected to a hand-lever, o, for the purpose of easily adjusting the frame and work to the right angle. The frame is then tixed in place by the sliding stop x and thumb-nut y. On the right-hand or face slide ofthe vertical -frame there is secured by bolts and nuts q q three curved arms of metal, A A A. On the ends of each .are V-shaped friction-rollers B B, the curved arms being hung orpivoted on their centers or so balanced that the rollers B B will adjust themselves to the circle o'f the revolving skeleton faceplate or open chuck C, which has a groove, c o, turned into the edge of its periphery, so that it hangs upon the friction-rollers and is driven by a cross-belt, E, passing around a projecting rim or pulley, F, connecting with the pulley Gr on the main driving-shaft S, which has one ot'its bearings in a box on the standard T. On the face 'ot' the revolving chuck C are three or more arms, D D D, projecting out far enough to receive and support the various size carriage-wheels. 0n cach of the arins D are placed clamps of metal d d d, With thumbscrews e e e, for the purpose of fastening the Wheel to the chuck C by clamping the fellies.

To facilitate the centering and adjusting the carriage-wheel to the skeleton face-plate so that the rim will run true when the boxes are titted in, I have invented and perfected an arrangement of mechanism which performs that thing to a certainty, as `well as other important functions, which are described as follows: To one of the upright posts V, I hinge a broad vbeam,Q, in such a manner that it can open and swing round soas to leave the chuck C free from` all obstructions on4 the rear side, convenient for trying in the common egon-boxes` when they are to be fitted in the outer end of thehub. The beam Q, when closed, is fastened by `a belt and screwnut, p. A metallathe-head, H, is titted on about the middleV of the beam Q, which has a sliding bar, It, working in i a'linc with the center of the revolving skeleton chuck C, the slide h being operated by a crank-pinion, and rack t" on the outer end of the slideh, which has on its square part an adjustable stop, k, to which a cord, Z, is fastened, which passes over a pulley, n, to a suspended weight, m. By this arrangement the slide and xtures are kept gently pressing againstthe end of the hub while it is being centered and secured to the chuck. On the end of the sliding bar h, I have lifted a hollow cone, I. When. desirable to center the wheel by the outer edge ofthe hub, the concave side o1' the.

t fit the box and cut or turn in the recess for washer or linch pin in the outer end.v of the hub. A recess o't' any desirable depth may be cut by putting a lip or a proper-shaped bit, o, on the end of the sliding `bar h. The head H may be moved from the center by sliding it on the beam Q and set, there being a mortise,f, through .the beam, with a bolt and thumb-nut for that purpose.

The arrangement of mechanism for holding the tool or cutter to bore or turn for iitting inthe box does not differ materially in its construction or operation from the common slide-rest en gine-lathe. However, in this connection I will give it a more full description.

On the `face side of the skeleton-chuck, on the right-hand endv of the frame platform, I place two timbers, K K, supported on four posts, L L L L, which are framed into the crosspieces Y Y. 0n the top ot'ythe timbers K K I place ways or guides N N ofrmeta-Linto whioha slide, O, istitted, there beingsecured on the top of the slide an adjustable toolholder,N, which, `being pivoted toward the other end, so that itmay be variedlaterally and secured at any desired` point by a regulating thumb-screw, o', thcshankof the cutter P is fitted into and `held in the y sockets p p. The tool may be broughtin contact with cates power and motion from the pulley F on the main shaft g to the pulley H on theyscr'ewshaftv b at the right-hand end of the machine, above which 'is `the forked standard W, `to support andform` the bearing of one end of the main driving-shaftg. y y y The great advantages of` my invention are that pipe or other boxesican be perfectly fit-ted into the hubs of wagon or carriage wheels, (no matter how tough orcross-grained the `wood may be,) so that the rim of the wheels will run true and track with each other; and, furthermore, the boxes can be titted into a set of four wheels in less-time than a single box can be fitted into one wheel by 'any other known process. y

Having thus fully describedmyiuvention, what I claim as new, and desire to secure by Letters Patent, is y i ,1. The skeletonface-plate or open revolving chuck supported in its place by self-adjusting friction-rolle1s on balanced arms,the rollers fitted to run in a groove'in the periphery of the chuck, to which .carriage-wheels" are attached for the purpose of iitting in pipe or other boxes constructed `and operated in the manner herein specified. i

2. The adjustable frame, to which the faceplate is attached, in. combination with the lever-arm, rule-scale, and indicator, to give tho hole in the hub the exactI taper of thepipe-box being fitted.

3. The arrangement of thc hingedbeam Q, the sliding bar h, and cutte'rq, the regulatingstop 7c, and weight m, with the reversiblecone I for centering the wheel, in the manner as described, for the purposes herein set; forth.
